Question

30 POINTS!! A horticulturist wants to produce geraniums with specific characteristics. She knows that the trait of red flowers is governed by the allele R (RR and Rr) and the trait of white flowers is governed by the allele r (rr).

A cross of two geraniums yields offspring that are 100% ​​Rr​​.
Which choice best represents the alleles of the parents?

Answer 1

Your answer is Rr and Rr (option C)

Answer 2

the correct answer is (c) Rr and Rr.

When two geraniums with the genotypes Rr and Rr are crossed, all of the offspring will be Rr. This is because both parents have one dominant R allele and one recessive r allele, so all of the offspring will inherit one of each.

Rr x Rr = 100% Rr
